Generic Connectivity
The E Series has been designed for SCADA and telemetry
applications, and any other applications that use an ASCII
communications protocol, and which connect physically using the
RS232 interface standard (although converters can be used to adapt
other interfaces such as RS422/485, RS530/V35, G703 etc).
Any protocol that can be displayed using a PC based terminal
program operating via a serial communications port is suitable for
transmission by the E Series radio modems.
An ASCII protocol is any that consists of message strings formed
from ASCII characters, that being defined as a 10 or 11 bit block
including start and stop bits, 7 or 8 data bits and optional parity bit(s).
Port set-up dialog that includes the expressions N,8,1, or E,7,2 or
similar indicate an ASCII protocol.
Most of the dominant telemetry industry suppliers utilise proprietary
ASCII protocols, and also common 'open standard industry protocols
such as DNP3, MODBUS, TCP/IP, and PPP. These are all ASCII
based protocols.
Industries and Applications
The E Series products are widely used in point-to-point and point-to-
multipoint (multiple access) applications for remote interconnection of
PLCs, RTUs, dataloggers, and other data monitoring and control
devices - including specialist utility devices (such as powerline
ACRs). In addition, other applications such as area wide security and
alarm systems, public information systems (traffic flow and public
signage systems) and environmental monitoring systems.
Application Detail
SCADA Systems
This is where one or more centralised control sites are used to monitor
and control remote field devices over wide areas. Examples include
regional utilities monitoring and controlling networks over entire shires
or a greater city metropolis. Industry sectors include energy utilities
(gas and electricity distribution), water and sewerage utilities,
catchment and environment groups (rivers, dams and catchment
management authorities).
Telemetry Systems
Dedicated telemetry control systems interconnecting sequential
devices either where cabling is not practical or distances are
considerable.
Examples include:
ore conveyor or slurry pipeline systems
simple water systems (pump and reservoir interlinking)
broadcast industry (linking studio to transmitter) etc.
Information Systems
Public Information systems such as freeway vehicle flow, travel time
monitoring, feedback signage, parking signage systems and
meteorological stations etc.

Part C Applications
Systems Architecture
Point-to-Point
This simple system architecture provides a virtual connection between
the two points, similar to a cable. Dependent of the hardware chosen,
it is possible to provide a full duplex connection (i.e. data transfer in
both directions simultaneously) if required.
Point-to-Multipoint Systems
In a multiple access radio system, messages can be broadcast from
one (master) site to all others, either using a half duplex radio system
or from any site to all others, using a simplex radio channel.
Half duplex systems often utilise a full duplex master, to make the
system simpler and for faster operation.
In either case, it will be necessary for the application to support an
addressing system, since the
master needs to be able to select
which remote device it with which
it wishes to communicate.
Normally, the radio system is
allowed to operate transparently,
allowing the applications protocol to
provide the addressing, and thus
control the traffic. Where the
application layer does not provide
the addressing, the E Series can
provide it using SID codes. (See
Part F - Operational Features)

E Series Data Radio User Manual

Part C Applications
Digipeater Systems
This configuration is used where all sites are required to communicate
via a repeater site. A repeater site is used because it has a position
and/or height advantage and thus provides superior or extended RF
coverage. The radio modem at the repeater does not have to be
physically connected to the applications master site. Information from
the applications master is transmitted to the repeater via radio, and the
repeater then relays this information to the other field sites. In this
scenario, the repeater is the master from an RF point of view, and the
application master is effectively a remote from an RF point of view,
even though it is controlling the data transfer on the system.
Backbone Store and Forward Systems
Store and forward is used as a way of extending RF coverage by
repeating data messages from one site to another.
This can be done globally using the inbuilt data repeating functions, or
selectively using intelligent address based routing features available in
some PLC/RTU protocols.
In this case it is necessary for all units on the system to operate in half
duplex mode (only key-up when transmitting data), so that each site is
free to hear received signals from more than one source.

Understanding RF Path
Requirements
A radio modem needs a minimum amount of received RF signal to
operate reliably and provide adequate data throughput.
In most cases, spectrum regulatory authorities will also define or limit
the amount of signal that can be transmitted, and the transmitted power
will decay with distance and other factors, as it moves away from the
transmitting antenna.
It follows, therefore, that for a given transmission level, there will be a
finite distance at which a receiver can operate reliably with respect to
the transmitter.
Apart from signal loss due to distance, other factors that will decay a
signal include obstructions (hills, buildings, foliage), horizon (effectively
the bulge between two points on the earth), and (to a minimal extent at
UHF frequencies) factors such as fog, heavy rain-bursts, dust storms,
etc.
In order to ascertain the available RF coverage from a transmitting
station, it will be necessary to consider these factors. This can be
done in a number of ways, including
(a) using basic formulas to calculate the theoretically available
signal - allowing only for free space loss due to distance,
(b) using sophisticated software to build earth terrain models and
apply other correction factors such as earth curvature and the
effects of obstructions, and
(c) by actual field strength testing.
It is good design practice to consider the results of at least two of these
models to design a radio path.

Part D System Planning and Design
Antenna Gain
By compressing the transmission energy into a disc or beam, the
antenna provides more energy (a stronger signal) in that direction, and
thus is said to have a performance gain over a basic omni antenna.
Gain is usually expressed in dBd, which is referenced to a standard
folded dipole. Gain can also be expressed in dBi, which is referenced
to a theoretical isotropic radiator. Either way, if you intend to send
and receive signals from a single direction, there is advantage in using
a directional antenna - both due to the increased signal in the wanted
direction, and the relatively decreased signal in the unwanted direction
(i.e. interference rejection properties).
Tuning the Antenna
Many antennas are manufactured for use over a wide frequency
range. Typical fixed use antennas such as folded dipoles and yagis
are generally supplied with the quoted gain available over the entire
specified band range, and do not require tuning. Co-linear antennas are
normally built to a specific frequency specified when ordering.
With mobile whip type antennas, it is sometimes necessary to
tune the antenna for the best performance on the required frequency.
This is usually done by trimming an antenna element whilst measuring
VSWR, or simply trimming to a manufacturer supplied chart showing
length vs frequency. These antennas would normally be supplied with
the tuning information provided.
Antenna Placement
When mounting the antenna, it is necessary to consider the following
criteria:
The mounting structure will need to be solid enough to withstand
additional loading on the antenna mount due to extreme wind, ice or
snow (and in some cases, large birds).
For omni directional antennas, it is necessary to consider the effect of
the mounting structure (tower mast or building) on the radiation pattern.
Close in structures, particularly steel structures, can alter the radiation
pattern of the antenna. Where possible, omni antennas should always
be mounted on the top of the mast or pole to minimise this effect. If this
is not possible, mount the antenna on a horizontal outrigger to get it at
least 1-2m away from the structure. When mounting on buildings, a
small mast or pole (2-4m) can significantly improve the radiation
pattern by providing clearance from the building structure.
For directional antennas, it is generally only necessary to consider the
structure in relation to the forward radiation pattern of the antenna,
unless the structure is metallic, and of a solid nature. In this case it is
also prudent to position the antenna as far away from the structure as
is practical. With directional antennas, it is also necessary to ensure
that the antenna cannot move in such a way that the directional
beamwidth will be affected. For long yagi antennas, it is often
necessary to instal a fibreglass strut to stablilise the antenna under
windy conditions.
Alignment of Directional Antennas
This is generally performed by altering the alignment of the antenna
whilst measuring the received signal strength. If the signal is weak, it
may be necessary to pre-align the antenna using a compass, GPS,
or visual or map guidance in order to find the wanted signal. Yagi
antennas have a number of lower gain lobes centred around the
primary lobe. When aligning for best signal strength, it is important to
scan the antenna through at least 90 degrees, to ensure that the centre
(strongest) lobe is identified.
When aligning a directional antenna, avoid placing your hands or body
in the vicinity of the radiating element or the forward beam pattern, as
this will affect the performance of the antenna.
Selecting Antennas
There are basically two types of antennas omni-directional and
directional.
Omnidirectional antennas are designed to radiate signal in a 360
degrees segment around the antenna. Basic short range antennas
such as folded dipoles and ground independent whips are used to
radiate the signal in a ball shaped pattern. High gain omni antennas
such as the co-linear compress the sphere of energy into the
horizontal plane, providing a relatively flat disc shaped pattern which
goes further because all of the energy is radiated in the horizontal
plane.
Directional antennas are designed to concentrate the signal into beam
of energy for transmission in a single direction (i.e. for point-to-point or
remote to base applications).
Beamwidths vary according to the antenna type, and so can be
selected to suit design requirements. The most common UHF
directional antenna is the yagi, which offers useable beam widths of
30-50 degrees. Even higher gain is available using parabolic dish
type antennas such as gridpacks.

Data Connectivity
The V24 Standard
The E Series radio modems provide two asynchronous V24
compliant RS232 ports for connection to serial data devices.
There are two types of RS232 interfaces DTE and DCE.
DTE stands for data terminal equipment and is generally applied to
any intelligent device that has a need to communicate to another
device via RS232. For example: P.C. Comm ports are always DTE,
as are most PLC and RTU serial ports.
DCE stands for data communication equipment and is generally
applied to a device used for sending data over some medium (wires,
radio, fibre etc), i.e. any MODEM.
The standard interface between a DTE and DCE device (using the
same connector type) is a straight through cable (i.e. each pin
connects to the same numbered corresponding pin at the other end of
the cable).
The V24 definition originally specified the DB25 connector standard,
but this has been complicated by the emergence of the DB9 (pseudo)
standard for asynch devices, and this connector standard has different
pin assignments.
The wiring standard is unbalanced, and provides for three basic data
transfer wires (TXD, RXD, and SG signal ground).
Hardware Handshaking
Hardware handshake lines are also employed to provide flow control,
however (in the telemetry industry) many devices do not always
support all (or any) flow control lines.
For this reason, the E Series modems can be configured for full
hardware flow control, or no flow control at all (simple 3 wire
interface).
Note: that when connecting devices together with differing handshake
implementations, it is sometimes necessary to loop handshake pins
in order to fool the devices handshaking requirements.
In telemetry applications (particularly where port speeds can be set to
the same rate as the radio systems over-air rate) then flow control,
and therefore handshaking, is usually NOT required. It follows that
any devices that CAN be configured for no flow control should be
used in this mode to simplify cabling requirements.
Handshaking lines can generally be looped as follows:
DTE (terminal) loop RTS to CTS, and DTR to DSR and DCE.
DCE (modem) - loop DSR to DTR and RTS (note-not required for E
Series modem when set for no handshaking).
RF Feeders and Protection
The antenna is connected to the radio modem by way of an RF feeder.
In choosing the feeder type, one must compromise between the loss
caused by the feeder, and the cost, flexibility, and bulk of lower loss
feeders. To do this, it is often prudent to perform path analysis first, in
order to determine how much spare signal can be allowed to be lost
in the feeder. The feeder is also a critical part of the lightning protection
system.
All elevated antennas may be exposed to induced or direct lightning
strikes, and correct grounding of the feeder and mast are an essential
part of this process. Gas discharge lightning arresters should also be
fitted to all sites.
Note: All ETSI installations require the use of a lightning surge
arrestor in order to meet EN6095. See Part A - Preface for lightning
arrestor specifications.

Power Supply and Environmental
Considerations
General
When mounting the equipment, consideration should be given to the
environmental aspects of the site. The cabinet should be positioned so
that it is shaded from hot afternoon sun, or icy cold wind. Whilst the
radios are designed for harsh temperature extremes, they will give a
longer service life if operated in a more stable temperature
environment. In an industrial environment, the radio modems should
be isolated from excessive vibration, which can destroy electronic
components, joints, and crystals.
The cabinet should provide full protection from moisture, dust,
corrosive atmospheres, and residues from ants and small vermin
(which can be corrosive or conductive). The radio modem will radiate
heat from the in-built heatsink, and the higher the transmitter duty
cycle, the more heat will be radiated from the heatsink. Ensure there is
sufficient ventilation in the form of passive or forced air circulation to
ensure that the radio is able to maintain quoted temperature limits.
Power Supply
The power supply should provide a clean, filtered DC source. The
radio modem is designed and calibrated to operate from a 13.8VDC
regulated supply, but will operate from 10-16 volts (filtered) DC.
The power supply must be able to supply sufficient current to provide
clean filtered DC under the full current conditions of the radio modem
(i.e. when transmitting full RF power). See Section L - Specifications
for more details of the power supply requirements.
Solar Applications
In solar or battery-backed installations, a battery management unit
should be fitted to cut off power to the radio when battery levels fall
below the minimum voltage specification of the radio. In solar
applications, a solar regulation unit MUST ALSO be fitted to ensure
that the radio (and battery) is protected from excessive voltage under
full sun conditions.
When calculating solar and battery capacity requirements, the constant
current consumption will be approximately equal to the transmit current
multiplied by the duty cycle of the transmitter, plus the receive current
multiplied by the (remaining) duty cycle of the receiver.
The Tx/Rx duty cycle will be entirely dependent on the amount of data
being transmitted by the radio modem, unless the device has been
configured for continuous transmit, in which case the constant current
consumption will be equal to the transmit current only (at 100% duty
cycle).
Note: Operation below the minimum specified supply voltages could
result in poor radio performance. If the supply voltage falls below
7.2Vdc the radio will shut down. Normal radio startup will not occur
until 10Vdc is supplied.
Site Earthing
The radio must not be allowed to provide a ground path from chassis
to (DB9) signal ground or (-) battery ground. Ensure that the chassis
mounting plate, power supply (-) earth, RTU terminal device, and
lightning arrester, are all securely earthed to a common ground point to
which an earth stake is attached. Please pay particular attention to
24Vdc PLC systems using DC-DC converters to supply 13.8Vdc.
Caution: There is NO internal replaceable fuse, and therefore
the radio modem MUST be externally fused with the fuse
holder provided (ER450: 3 amp slo-blow fuse, EB450: 5
amp fast-blow fuse).

Introduction
Welcome to the ER450 Quick Start Guide. This guide provides step-
by-step instructions, with simple explanations to get you up-and-
running.
Mounting and Environmental
Considerations
The ER450 radio comes complete with a mounting cradle and is
attached to a panel or tray by means of screws or bolts, using the hole
slots provided.
Note: In high power or high temperature applications, it is desirable to
mount the radio with the heatsink uppermost to allow ventilation for
the heatsink.
The radio should be mounted in a clean and dry location, protected
from water, excessive dust, corrosive fumes, extremes of temperature
and direct sunlight. Please allow sufficient passive or active ventilation
to allow the radio modems heatsink to operate efficiently.

Connecting Antennas and RF Feeders
The RF antenna system should be installed in accordance with the
manufacturers notes.
The RF connector used on the E Series radios are N Type female
connectors. Always use good quality low loss feeder cable, selected
according to the length of the cable run. Ensure all external
connections are waterproofed using amalgamating tape.
Preset directional antennas in the required direction using a compass,
GPS, or visual alignment and ensure correct polarisation (vertical or
horizontal).
Communications Ports
System Port RJ45
The System Port (available front and rear on EB/EH450) is a multi-
function interface used for:
Programming / Configuration of the radio
Remote Diagnostics connections
To access these functions use theTVIEW+ Cable assembly (RJ45
Cable and RJ45 to DB9 Adaptor).
The TVIEW+ Cable is a standard CAT 5 RJ-45 (Male) to RJ-45
(Male) patch cable. It is intented for RS232 serial communications
only and should not be connected directly into an ethernet port of a
PC. The Cable must be used in conjuction with the RJ-45 to DB9
Adaptor.
TVIEW+ Adaptor Configuration:
Special user pinouts:
Shutdown (Pin 4) - Active low for power save function
External PTT (Pin 8) - Provides a manual PTT override facility
for enabling the transmitter. For testing this can be activated by
connecting PTT (Pin 8 ) to Gnd (Pin 7).

User Interfaces Ports A & B
Each user port (A & B) is wired as a RS232 DCE, configurable for no
handshaking (3-wire) interface, or for hardware or software (X-on/X-off)
flow control. In most systems flow control is not required, in which
case only 3 wires need to be connected between the radio and the
application device.
Typical pins used:
Pin 2 (RxD) - data output from the radio modem,
Pin 3 (TxD) - data input to the radio modem,
Pin 5 (SG) - signal ground.
See Part D System Planning and Design - Data Connectivity, for
further details of other cable configurations.

Activating the Transmitter
In most systems, the transmitter by default is controlled automatically
by the radio when it has data to transmit.
In some systems, such as full duplex point-to-point links or full duplex
point-to-multipoint base stations, it is desirable to run the transmitter all
the time (hot keyed).
Two mechanisms are provided to do this:
the radio modem can be configured to transmit continuously
whenever powered, or
the radio modem can be configured to transmit whenever an
external RTS signal (Pin 7) is applied to one (or either) user
ports. (To simulate an external RTS input, loop pins 6 to 7).
To operate in these modes, the radio must be configured via the
programming software.
Caution: When the radio is configured to transmit
continuously, ensure an RF load is present BEFORE
applying power to the unit.

Power Supply Requirements
The E Series radio modem is designed and calibrated to operate from
a filtered 13.8Vdc regulated supply, but will operate from a 10-16Vdc
(11-16Vdc for EB450 & EH450) range. See Section L - Specifications
for more details on power supply requirments
Caution: There is NO internal replaceable fuse, and therefore
the radio modem MUST be externally fused with the fuse
holder provided (ER450: 3 amp slo-blow fuse, EB450: 5
amp fast-blow fuse, EH450 1 amp slo-blow fuse).
The radio is designed to self protect, and will blow the external fuse if
the voltage exceeds 16Vdc, or if reverse polarity is applied.
The radio modem can also be damaged if there is any potential
difference between the chassis-ground, RS232 signal ground, power (-
) input, or antenna coaxial shield. Before connecting any wiring,
ensure all components are earthed to a common ground point (please
pay particular attention to 24V PLC power systems where converters
are used).
Connect the antenna and RS 232 plugs BEFORE applying power to
the unit.
Lastly, before inserting the power plug, please re-check that the
polarity and voltage on the power plug is correct using a multimeter.

Optimising the Antenna for best RX
signal
Once the unit is operational, it is important to optimise the antenna
tuning.
In the case of a directional antenna, it will be necessary to align the
antenna for the best received signal.
This can be done by using the (0-5Vdc) output on Pin 9 of Port B to
indicate signal strength (RSSI). This voltage can be converted to dBm
using the chart below.

If all the LEDs are off, no power is reaching the radio modem.
Successful power-up is indicated by the PWR LED indicating a
continuous (healthy) GREEN state. Note that this LED is turned RED
when the transmitter is active.

Radio Errors
Internal radio management software monitors many aspects of the
radio hardware. Under certain circumstances radio faults may prevent
normal operation. In the event that these fault conditions occur, the
radio will enter an ERROR state and this will be indicated by flashing
ALL LEDs RED, then flashing a pattern of GREEN LEDs. The pattern
of all GREEN LEDs represents the specific type of error that has
occurred. See Table below.

Pwr/TX Error Diagnosis
OFF OFF OFF ON External Supply Voltage
out of spec. (1)
ON OFF ON OFF RX VCO Out of Lock. (2)
ON OFF OFF ON TX VCO Out of Lock. (3)
All other patterns indicate serious hardware errors. Please record this
pattern and return the result with the service return information.
Note (1): If external voltage is too high (>16Vdc) radio damage may
occur. If the external voltage is too low (<10Vdc) the radio may not
operate within specifications.
Note (2) and (3): If the radio receiver or transmitter frequencies are
programmed outside the specified frequency ranges (model type
dependent), then normal radio operation may not be possible. In this
case, use TVIEW+ to set the receiver and/or transmitter frequencies to
be within the specified range. If this error occurs and the frequencies
are within the specified frequency ranges (model type dependent), the
radio will need to be returned for service.

Received Signal Indicator
The RX/SYNC LED is used to indicate the state of the receiver.
If the LED is off, no signal is being received.
A RED indication shows that an RF carrier is being received, but no
data stream can be decoded. This will briefly happen at the very start
of every valid received transmission or may indicate the presence of
interference, or another user on the channel.
A continuous GREEN indication shows that the modem is locked and
synchronised to the incoming signal, and has excellent Bit Error Rate
(BER). Any losses of synchronisation (BER errors) are shown as a
visible RED flicker of the LED.
Note: This might only be apparent on a PTMP slave when only
receiving.
Verifying Operational Health
It is possible to verify the operation of the radio modem using the
indicators provided by the unit. The state of the transmitter and
receiver, and data flow can be interpreted by the indicator LEDs (see
below).
Note: Port A and Port Bs RxD and TxD will be Active on Data Flow
Data Flow breakout LEDs
There are also two LEDs to indicate data flow into and out of the two
user ports.
Input data to be transmitted is shown as a RED flash, and received
data to be output to the port is shown as a GREEN flash.
If data is alternately flowing in and out quickly, then the indicator
appears orange.

EB450 Quick Start Guide
Introduction
Welcome to the Quick Start Guide for the EB450 Base / Repeater
Data Radio. This guide provides step-by-step instructions, with simple
explanations to get you up-and-running.
Mounting and Environmental
Considerations
The EB450 Base Station is housed in a 2RU 19 rack enclosure. The
4 mounting holes on the front panel should be used to secure the unit to
the rack.
The radio should be mounted in a clean and dry location, protected
from water, excessive dust, corrosive fumes, extremes of temperature
and direct sunlight. Please allow sufficient passive or active ventilation
to allow the radio modems heatsink to operate efficiently.
All permanent connections are made at the rear of the unit. This
includes: Power, Antenna, Communications Ports, Digital I/O and
System Port. The front panel has an additional System Port
connection point for easy access.
Full Duplex Considerations
The EB450 is designed for continuous full duplex transmission. An
automatic thermostatically controlled fan will operate whenever the
internal temperature exceeds 50 degrees Celsius.
External Duplexer Considerations
The EB450 is normally supplied with separate Tx and Rx ports for
connection to an external duplexing system.
Depending on the frequency band of operation and the Tx/Rx
frequency split, internal band reject duplexers are available.
